About this puzzle

Crow 40x40 Nonogram is a hard 40x40 picture nonogram from the bird collection. Coverage sits near 24% (386 of 1600 cells), giving you an open, sparsely filled picture to uncover.

The biggest single run here is 26 cells long — fill that first and the surrounding lines fall into place faster. Most solvers clear a board like this in around 25 minutes.

How to solve this nonogram

On a large board, divide it into zones: lock in the longest clues, mark proven-empty cells with X, and only then chase the tight lines. Because the picture is sparse, X marks for empty cells do most of the heavy lifting — flag them generously. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
